State officials say 40,000 New Yorkers have signed up for health insurance in the first week of operation for the new state-run marketplace that includes low-cost plans.

The New York State of Health says its website has quadrupled capacity since opening enrollment Oct. 1, resolving the issues that initially kept many consumers from advancing past the home page, and says it is running smoothly.

The related customer service center operators have responded to more than 26,000 callers, though officials say most of the 40,000 enrollments have been online.

The website is open daily with scheduled maintenance from midnight to 6 a.m.

The call center is open 8 a.m. to 8 p.m. weekdays and 9 a.m. to 1 p.m. Saturdays at 1-855-355-5777.
